BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to adjustable shoes. More specifically, my invention is primarily intended as adjustable bowling shoes capable of being well fitted and providing necessary side support to feet of different shapes and sizes.

[0003] 2. Description of the Prior Art

[0004] Many activities, particularly bowling, require people to wear special shoes in the activity area. People usually do not purchase those special shoes, but rather rent them from the facilities when they attend those activities. Those facilities generally provide shoes of all sizes. One problem is that sometimes people just do not know what size of the shoes can provide a good fit to their feet. The other problem is that even though people do know the size of the shoes, the shoes of that size might still not be capable of providing a perfect fit to their feet due to the limited number of shoe sizes and the unlimited size variations of people's feet.

[0005] Various devices have been created in an attempt to solve these problems. For example, U.S. Pat. No. 5,682,687 discloses a stretchable shoe. The stretchable shoes include a shoe body divided into a front section and a rear section. The front section includes a front sole and a front inner sole each of which is formed so as to rearwardly extend by a predetermined length in a tongue-like manner and the rear section includes a rear sole which is provided on a lower surface thereof with a heel having a front edge. The rear section is provided on a portion of an upper surface thereof corresponding to the heel with a first velvet-type fastener and formed with an elongate guide hole elongatedly extending in a longitudinal direction thereof. The front sole of the front section is inserted at a rear body portion thereof through the front edge of the heel into an inside of the heel and mounted thereon with a pin so as to vertically extend therefrom. The pin is fitted in the elongate guide hold of the rear sole of the rear section to join the rear section and front section to each other, resulting in providing the shoe body. The front inner sole has a second velvet-type fastener mounted on a lower surface of a rear end thereof, which second velvet-type fastener is detachably engaged with the first velvet-type fastener mounted on the upper surface of the rear sole of the rear section to unite the front section and rear section to each other. However, the front section of the shoe body of the stretchable shoes is not capable of being adjusted to fit shapes and sizes of different midfoot, forefoot and toe. The rear section of the shoe body of the stretchable shoes is not capable of fitting shapes and sizes of different heel. Neither the front section of the shoe body, nor the rear section of the shoe body, nor the combination of these two, is capable of providing necessary side support to feet of different sizes.

[0006] U.S. Pat. Nos. 5,659,980 and 5,570,523 disclose an adjustable shoe for an adult and a child. Both shoes contain a heel, front portion, back portion, toecap and insole where the front portion has a plurality of positioning protrusions. The toecap contains an adjustable pad with a plurality of positioning holes. The protrusions are inserted into the corresponding holes in order to adjust the length of the shoe size. The sides and the heels of the shoes contain fastening pads which connect to each other to hold the different parts of the shoes together. The heel further contains socket buttons to join with ball buttons to further adjust the shoe. Again, the front portion of the shoe is not capable of being adjusted to fit shapes and sizes of different midfoot, forefoot and toe. Neither the front portion of the shoe, nor the rear body portion of the shoe, nor the combination of these two, is capable of providing necessary side support to feet of different sizes

[0007] U.S. Pat. No. 4,969,277 discloses an adjustable shoe particularly designed for women. The shoe contains a first portion, two side portions, a top portion and a back portion. The top portion is a shoe flap like member which folds over the tip of the foot and attaches to the side member by Velcro or a hook and loop fastener. The back portion is split into two sides which connect to each other by Velcro or hook and loop fasteners. Thus, the shoe is worn by opening the shoe flap and back portion and is adjusted to the foot size. However, the shoe is not capable of being adjusted in its length.

[0008] What is needed then is shoes capable of being adjusted to fit different midfoot, forefoot, toe, and heel shapes and sizes, and also capable of providing necessary side support to the foot at the same time.

[0009] Accordingly, it is a principal object of my invention to provide adjustable shoes, which are capable of being adjusted in length, width, and height to provide a perfect fit to feet of different shapes and sizes.

[0010] It is a further object of my invention to provide adjustable shoes, which are capable of providing necessary side support to feet of different shapes and sizes.

[0011] Other objects of my invention, as well as particular features, elements, and advantages thereof, will be elucidated in, or apparent from, the following description and the accompanying drawing figures.

SUMMARY OF THE INVENTION

[0012] According to my present invention, I have provided an adjustable shoe capable of being well fitted to feet of different shapes and sizes. The adjustable shoe includes a two-part sole structure, comprising a rear sole member and a forward sole member, a shoe body, comprising a rear body portion and a forward body portion, a heel, a left-side fastener structure, a right-side fastener structure, and a top fastener structure.

[0013] The rear sole member has a bottom guide member, extending forwardly in a longitudinal direction, a forward sole member having a bottom guide way, which is sized and shaped for receiving the bottom guide member for enabling relative movement of the rear sole member and the forward sole member into a selected adjusted position corresponding to the length of the foot being fitted within the shoe.

[0014] The heel is positioning under the two-part sole structure, and is mounted under the rear sole member.

[0015] The rear body portion having stiffener, mounted on the rear sole member, has a left guide member on the left side, extending forwardly in a longitudinal direction, and a right guide member on the right side, extending forwardly in a longitudinal direction. The rear body portion has yieldable opposing sides, which are capable of being relatively movable for matching the heel shape of the foot being fitted within the shoe.

[0016] The forward body portion is mounted on the forward sole member. The forward body includes a left shoe flap having a left guide way, which is sized and shaped for receiving the left guide member for enabling relative movement of the rear body portion and the forward body portion into a selected adjusted position corresponding to the length of the foot being fitted within the bowling shoe, and a right shoe flap having a right guide way, which is sized and shaped for receiving the right guide member for enabling relative movement of the rear body portion and the forward body portion into a selected adjusted position corresponding to the length of the foot being fitted within the shoe.

[0017] The left-side fastener structure is selectively adjustable for matching and holding different foot length to fit the foot being fitted within the shoe, with one part mounted on the left shoe flap and the other part mounted on the rear body portion.

[0018] The right-side fastener structure is selectively adjustable for matching and holding different foot length to fit feet of different sizes, with one part mounted on the right forward body member and the other part mounted on the rear body.

[0019] The top fastener structure is selectively adjustable for matching different shapes and sizes of different midfoot, forefoot and toe to fit feet of different shapes, with one part mounted on the left shoe flap and the other part mounted on the right shoe flap.
